Authorities have previously uncovered the remains of three people in flower pots on a property where he was said to have stored his tools.

On Thursday (8 February) police told reports that they have recovered the remains of six people and have the DNA profiles of two people, one of which was Kinsman's, but did not say who the other profile belonged to.

Det. Sgt. Hank Idsinga says more charges are expected against McArthur after the remains were found in large planters at the property in Mallory Crescent in the Toronto neighbourhood of Leaside.

BBC News reported that McArthur had a deal with the home's elderly residents where he would care for their lawn for free, if he could store his landscaping equipment there.
